Improvement in gate and door closing device



UNITED STATES PATENT OFFICEo GEoRGE TURNER,v oE LANSING, MICHIGAN.

Specification forming part of Letters Paten-t No. 41,348, dated March15, 1864.

To all whom it may concern:

Be it known that I, GEORGE TURNER, of Lansing, in the county of Inghamand Stafe of Michigan, have invented a new and Improved Gate and DoorClosing Device; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings,makinga part of this specification, in which-Figure l is aperspective view of my invention. Fig. 2 is a plan or topview of the same. Fig. 3 is a diagram showing theapplication of theinvention to either a right or left hand gate.

Similar letters of reference indicate corresponding parts in the severalfigures.

The invention relates to an improvement in the old and well-knownweight-and-pulley attachment for closing do0rs,and is also designed tosupersede the ordinary weight-and-cha'n attachment for closing gates.

The invention consists in the employment or use of a xed and aself-adjusting pulley arranged in such a manner that the device may beapplied to either a right or a left hand door or gate, and operateequally well vin either application without the liability of the cordslipping from the pulleys in any position of the door or gate, theweight at the same time being entirely'out of the way.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents an arm,which may be of castiron, and having at one end twoplates, a a, which are at right angles with each other,said plateshaving holes in them, thrpugh which screws pass to secure the arm Atothe angle ofthe door or gate-post B, as will be understood by referringto Fig. 3. v

At the outer or opposite end of the arm A there is a vertical fixedpulley, O, the axis b of which has its bearings in pendants c c, so thatthe upper surface of the pulley C will be below the top of the arm, asshown clearly in Fig. I.

To the outer end of the arm A there is attached bya pivot-bolt, d, aplate, D, which is allowed to work on the bolt d a certain distance,either to the right or left, as will be understood by referring to Fig.2, in which the plate D is shown in one position in black and in theother in red. This movement of the plate D is limited. by means ofshoulders e at the under side of the arm A, and similar shouli ders, f,at the under side of the plate D. (See Fig. 1 anud dotted lines in Fig.2.)

At the under side of the front part of the plate D there is a horizontalpulley, E, which is fitted loosely on a vertical pendent axis, g,attached to plate D. The periphery of the pulleys E and C are of concaveform, and the center of the periphery of the pulley E is in line, ornearlyso, with the center of the upper part of the periphery of thepulley C, so

that the rope or cord (shown in red) which l passes over the pulley Cwill pass in a horizontal line around the pulley E, as shown in red inFig. 1.

The arm-is secured by screws or bolts to the post to which the door orgate is hung, said arm projecting angularly from the post at the door orgate side, in consequence of the plates a a abutting against twoadjoining sides. of it, las shown in Fig. 3. The rope or cord isattached to the door or gate at about one-third the distance of itswidth from its free :or unhinged end.

v From the above description it will be seen that as the door or gate isopened and closed the weight will riseand fall by the side of the postto whichthe arm A is attached, and to which the door or gate is hung,the pulleyE serving as a guide to keep the cord or rope properly on C.rIhe pivoted plate Dadmits of the arm A being attached to the post ofeither a right l or left hand door or gate, as will be seen by referringto Fig. 3,'in which the arm A is shown in red attached to an oppositepost. By this adjustment of the plate D the pulley E, which is attachedto it, is allowed to adj ust itself in line with the xed pulley U whenthe arm A is attached to either post.

By this arrangement the weight is entirely out of the way, and is farpreferable to the swinging chain and weight hitherto applied to gates,as the latter arrangement is frequently in the way, and the Weight has avery unequal action on the gate. My invention may also be advantageouslyapplied to doors when a weight is preferred to a spring for closingthem.

rIhe pulleys C E, in consequence of being below or unllerueatll the armA and plate D, combination with an adjustable plate, D, pivare fullyprotected from snow and ice in Winoted to A and having a horizontalpulley, E, ter. 1 4fitted to it, all arranged to operate in themaul-Iaving thus described my invention, what 11er substantially as andfor the purpose here- I claim as new, and desire to secure by Letters inset forth.

Pateut,isi GEORGE TURNER.
